Checking timing on a 22RE

I am trying to set the timing on my 85 Runner. I've set timing hundreds of times before, so it should be no big deal, but the manual says to short the two contacts in the T connector to get the proper reading from the gun, and I can not find anywhere that shows where the T connector is. Could someone please help me out so I can quit scratching my head and staring at the engine compartment like a moron? Thanks.

Look behind the air cleaner box near the inner fender for a round plug with only 2 wires going to it.

Is it EFI? dont know if it matters.

It is EFI, and I think there are 3 plugs in that location fitting that description. Any idea what the wires should be running to or from to give me an idea of which plug it might be?

Yup, just short the one that has 2 wires going to it, if you dont short it, the timing will be jumping all over.

On my 87 with EFI there is a DIAGNOSTICS plug next to the battery on the passenger side, there are like 15 holes im not sure which one it is but I belive you can get this info for free from the dealer or in a Chiltons manual, Either way just take a paper clip and Stick it in the correct holes, This turns of the Electronic Timing adjustment so it can be fine tuned. dont try and time it without shorting this you will just mess things up.

PS first time I tried I shorted out my ecu Fuse, and my Truck died on the spot and didnt start, I then paniked untill I checked my fuse to find a simple burned fuse. So be carefull you get the right ones

on my son's 85, there are 2 plugs that fit into two rubber grommets near the air box. You pull it out of the grommet and put a jumper wire across the two contacts. It should be the smaller of the 2.

Yes, but it is a different connector. The connector it located next to the fuse box inside the engine compartment on the passenger side. It has a grey cover and says "diagnostics" on it. You jumper out the pins TE1 & E1.

On an 85, it has the old diagnostic plugs. They are behind the airbox, there should be 2 or 3 just sitting there or in the rubber plugs, but you need the one with the 2 wires going in the back of it. You will know it is the right one when your check engine light flashes. So just jump the 2 wires and adjust your timing

Greg here's a pic from Roger Brown's site. The connector you want is circled in blue.

jumper diagram

chilton's manual is great check emmision controls page 4-47 and you'll find the diagram you need. you'll find the fuse box near the battery on the passenger side and on its side is the diagnostics box if standing at the front of the car the box appears 6 notches 2x3 2 notches then 9 3x3 in the 3x3 section the middle is te1 and the bottom right is e1 cross those to flash the display

I have a 91 pickup with a 22re i jumped the pins te1 &e1 and with the timing light my mark was still jumping all over the place...i checked all my plug wires and they are making good contact...any idea what may be causing it? It doesnt have a studder or really feel like its lacking power but i have a feeling it wont pass smog because of it
